Got a Call from Christopher today. “I do a lot of EDACs” I said. He said “what you really want is the CB37 Light Director Board“
And he was right.

I’ve been calculating a lot of components in series lately for an ECR255 class. I’ve also had to graph them on impedance diagrams and a power triangle.
In an effort to better understand the math I made a calculator for myself. Here is it for you to use and enjoy. If you see any problems please let me know. It was designed in excel 2011 for mac… there WILL be compatibility issues and I hope they’re minor.
How it works:
You can fill int the info you have in the orange boxes. Once the boxes are filled in the calculator should fill in the rest.
If you need to modify anything else, it’s all dependant on the orange boxes. I suggest a goal seek by modifying and orange cell.
In the 70’s and into the 90’s WBS used a Schadow switch in almost every product they built. Different buttons required different offsets so “GOLDEN RULES” of design were made up so each engineer was on the same page. I found two of those pages the other day and was fascinated. These drawings are both done by hand and are admirable.

Check out Jörg Wuttke, Understanding Microphones
Jörg Wuttke was born in Berlin in 1942. He studied electronics and telecommunications at Karlsruhe University, specializing in acoustics, and was teaching assistant to professor Günther Kurtze, the inventor of the shotgun microphone. He joined Schoeps GmbH as a research engineer in 1970, became its chief engineer in 1972, and is now its technical director.
Mr. Wuttke has been an active member of the Audio Engineering Society for many years, including publishing in the AES Journal and presenting papers and chairing workshops at conventions. In1993 he was awarded an AES Fellowship. Since 1972, he has been a member of the DIN standards committee on microphones and headphones. He maintains an avid interest in listening to music and recording live concerts.

What Is The Best Way to Learn Something New?
Anthony P. Kuzub
Everyone learns in his or her own way. As an adult returning to school, there have been many strategies to getting the best value from the academic industry. Time, both in and out of class, is lost income for many learners. Wondering if there was: a more efficient and effective way of learning new concepts, a strategy for processing fresh information, and an approach for subject retention, seemed a worthy topic. How to Learn Better at Any Age (Brown, Roediger, & McDaniel, 2014) and How Classroom Teachers Can Help Students Learn and Teach Them How to learn (Kiewra, 2002) are two great resources on the topic. Both articles stress similar factors and compliment each other but Brown et al. push the argument towards the right answer.
“Instructors who present information so effectively that students are compelled to learn in effective ways are good “fish givers.” They give students the means to learn what is being taught right now. What more can instructors do? Be fishing teachers” (Kiewra, 2002)
“When learning is harder, it’s stronger and lasts longer”
(Brown, Roediger, & McDaniel, 2014).
Effective learning is broken down into three parts done in an organized way: intake, practice, and self-testing. The best way to learn: is a lesson you can properly ingest; with ‘questions from yourself’ and ‘questions to yourself’.
“You usually cannot embed something in memory simply by repeating it over and over. Rereading has three strikes against it: It is time-consuming; it doesn’t result in durable memory and it invokes a kind of unwitting self deception, as growing familiarity with the text comes to feel like mastery of the content.” (Brown, Roediger, & McDaniel, 2014)
Classroom lessons are the most expensive way to learn, using this time efficiently is to the learners benefit. To make classroom lectures effective, Kiewra advocates that teachers provide skeletal note-taking devices. These devices encourage attention and focus on the material presented in lectures. Such devices should include: pre-prepared point form user format-able packets of core concepts with matrix style illustrations (for simplified reference) and practice questions. Learners can format the layout of this information to whatever medium they prefer to read with. Emerging software allows users to create their own audio books, read everywhere, and take advantage of speed-reading technologies like Spritz. These outside tools compliment classroom mentoring. With these augmented experiences, learners can easily take “a single, simple quiz after reading a text or hearing a lecture [that] produces better learning and remembering than rereading the text or reviewing lecture notes.” (Brown, Roediger, & McDaniel, 2014) Notes are external information, not internalized knowledge. Having personalized notes make for easy retrieval. “Recalling facts or concepts from memory — is a more effective learning strategy than review by rereading.” (Brown, Roediger, & McDaniel, 2014)
“Practice makes perfect. But, perfect practice makes permanent.”
Mr. Vince Lombardi
Comprehension of new material is best achieved through practice. Practice inspires questions that classroom lectures cannot provide. This engagement has long-term benefits and allows greater comprehension of the subject material being learned. Practice must be tailored to the learners learning style and to their unique intelligence. “Periodic practice arrests forgetting, strengthens retrieval routes, and is essential for hanging onto the knowledge you want to gain.” (Brown, Roediger, & McDaniel, 2014) Comprehension allows the learner visualize, recall, predict, and connect with material. practiced knowledge. If the learner makes personal connections they can evaluate problems and synthesize answers more effectively and accurately. “Flashcards and example tests are a simple example. Retrieval strengthens the memory and interrupts forgetting.” (Brown, Roediger, & McDaniel, 2014) Practice and instant self-monitored feedback of learned material creates long last knowledge.
Self Testing, delivered in whatever form that is reflective of ‘measure of the learned material’, – should be make freely available through online resources. Self-testing material is more effective than the re-reading lengthy material. “Instructors can facilitate self-testing by providing students with previous tests or practice tests as study device. [Teachers could] assign students to generate practice tests.” (Kiewra, 2002) Making mistakes, and being able to learn from them, comes through practice and implementation of concepts. Self-testing is a mirror to knowledge. Having personalized practice is : “… giving new material meaning by expressing it in the learners own words and connecting it with what they already know.” (Brown, Roediger, & McDaniel, 2014) Mistakes, in application, are made through hands on experience.is an option worth embracing; it is a necessity to overcome learning obstacles. “Self-explanations are statements learners make as to why certain ideas are so. Learners should test themselves so thoroughly prior to an exam that there is nothing the instructor can ask them that they haven’t already asked themselves” (Kiewra, 2002) Learners asking “what’s on the test?” are looking for guidance in practice. What’s on the test is the reflection of good instruction and good practice.
Kiewras wrote an enjoyable academic review on the approach to teaching. It was a sort of ‘wakeup call’ for “fish giving teachers” to become “Angling Technology 112.7FLY instructors at the school of choice. Learners are choosing their own adventure, and their hard work always pays off. Brown et al. say it best in that “the elements that shape your intellectual abilities lie to a surprising extent within your own control.” (Brown, Roediger, & McDaniel, 2014). For an instructor the best pupils: are the ones who want to be there, who want to learn, and who want to be good at something. If there is a meaningful rewarding lesson in the work, with someone there to tell them: “how to know” and “what to avoid”, they’ll be okay.

As a part of my school program, I’ve decided to take a shot at re-designing 2 WBS components.
First the 4-110 mic pre-amp for the M460 – M461. In the 90s WBS redesigned the card using 5534 but I’m looking at something even more modern.
Second the 109 cards. While at Revolution Recording, Joe D redesigned his version of the 109 card and it was a HUGE improvement. He described it as “taking the cheese cloth off the audio” and he was right.
The idea is to have a plug and play module available for users with a few new features not incorporated in past designs.
Once they’re done I hope to have them for sale on www.AudioAholics.com
Jeff and Sydney did some fantastic work while I was at Revolution Recording. They’ve setup a killer room downtown and have Wizard Services to offer. Here is a great lesson from a very learned man.
